A user is connected to an Amazon EC2 instance in a private subnet. The user is unable to access the internet from the instance by using the following curl command: curl http:/www.example.com.
A SysOps administrator reviews the VPC configuration and learns the following information:
* The private subnet has a route to a NAT gateway for CIDR 0.0.0.0/0
* The outbound security group for the EC2 instance contains one rule: outbound for port 443 to CIDR 0.0.0.0
/0
* The inbound security group for the EC2 instance allows ports 22 and 443 from the user's IP address.
* The inbound network ACL for the subnet allows port 22 and port range 1024-65535 from CIDR 0.0.0.0/0 Which action will allow the user to complete the curl request successfully?
A. Add an additional outbound security group rule for port 80 to CIDR 0.0.0.0/0.
B. Add an additional inbound network ACL rule for port 80 to CIDR 0.0.0.0/0.
C. Add an additional inbound security group rule for port 80 to CIDR 0.0.0.0/0.
D. Add an additional outbound security group rule for port 80 to the user's IP address.
正解：A
解説：
Since the EC2 instance is attempting to access the internet using HTTP (port 80) but is configured only to allow HTTPS (port 443) traffic, the security group needs adjustment:
* Security Group Configuration: The outbound rules of the security group associated with the EC2 instance must allow traffic over HTTP. Add an outbound rule that enables port 80 to destination 0.0.0.0
/0. This rule will allow the instance to send HTTP requests to any IP address on the internet.
* Test Connectivity: After updating the security group, test the connectivity using the curl command again to ensure the configuration allows internet access via HTTP.
This change is necessary because the existing security group configuration does not permit outbound HTTP traffic, which is essential for accessing websites using HTTP.

A company hosts an application on Amazon EC2 instances. The instances are in an Amazon EC2 Auto Scaling group that uses a launch template. The amount of application traffic changes throughout the day. Scaling events happen frequently.
A SysOps administrator needs to help developers troubleshoot the application. When a scaling event removes an instance, EC2 Auto Scaling terminates the instance before the developers can log in to the instance to diagnose issues.
Which solution will prevent termination of the instance so that the developers can log in to the instance?
A. Use Amazon Inspector to configure a rules package to protect the instances from termination.
B. Use Amazon GuardDuty to configure rules to protect the instances from termination.
C. Update the Auto Scaling group by enabling instance scale-in protection for newly launched instances.
D. Ensure that the Delete on termination setting is turned off in the UserData section of the launch template.
正解：C
質問 # 415
A company stores sensitive data in an Amazon S3 bucket. The company must log all access attempts to the S3 bucket. The company's risk team must receive immediate notification about any delete events.
Which solution will meet these requirements?
A. Enable S3 server access logging for audit logs. Set up an Amazon Simple Notification Service (Amazon SNSJ notification for the S3 bucket. Select DeleteObject tor the event type for the alert system.
B. Enable S3 server access logging for audit logs. Launch an Amazon EC2 instance for the alert system. Run a cron job on the EC2 instance to download the access logs each day and to scan for a DeleteObject event.
C. Use Amazon CloudWatch Logs for audit logs. Launch an Amazon EC2 instance for The alert system. Run a cron job on the EC2 Instance each day to compare the list of the items with the list from the previous day. Configure the cron job to send a notification if an item is missing.
D. Use Amazon CloudWatch Logs for audit logs. Use Amazon CloudWatch alarms with an Amazon Simple Notification Service (Amazon SNS) notification for the alert system.
正解：A
解説：
To meet the requirements of logging all access attempts to the S3 bucket and receiving immediate notification about any delete events, the company can enable S3 server access logging and set up an Amazon Simple Notification Service (Amazon SNS) notification for the S3 bucket. The S3 server access logs will record all access attempts to the bucket, including delete events, and the SNS notification can be configured to send an alert when a DeleteObject event occurs.

A SysOps administrator has an AWS CloudFormation template of the company's existing infrastructure in us-west-2. The administrator attempts to use the template to launch a new stack in eu-west-1, but the stack only partially deploys, receives an error message, and then rolls back.
Why would this template fail to deploy? (Choose two.)
A. The template referenced an IAM user that is not available in eu-west-1.
B. The template referenced an Amazon Machine Image (AMI) that is not available in eu-west-1.
C. CloudFormation templates can be used only to update existing services.
D. The template requested services that do not exist in eu-west-1.
E. The template did not have the proper level of permissions to deploy the resources.
正解：B、D
質問 # 417
A company is using an Amazon DynamoDB table for data. A SysOps administrator must configure replication of the table to another AWS Region for disaster recovery.
What should the SysOps administrator do to meet this requirement?
A. Enable DynamoDB Streams, and add a global secondary index (GSI).
B. Enable point-in-time recovery.
C. Enable DynamoDB Accelerator (DAX).
D. Enable DynamoDB Streams, and add a global table Region.
正解：D
解説：
By enabling DynamoDB Streams, you can capture changes (inserts, updates, and deletes) made to the DynamoDB table. This stream of changes can then be replicated to another AWS Region using the Global Table feature of DynamoDB. Global Tables automatically replicates the data across multiple AWS Regions, providing a fully managed, multi-Region, and multi-master database.
